                    Geology, Soils, Climate

• The Edward’s Plateau is formed from hard limestone.
• Erosion of the limestone has formed thousands of caves of all sizes
in the region, including the Edwards Aquifer

• Soils tend to be clays as well as very shallow with have little
organic matter.

• Austin receives > 30 in. precipitation/year. It gets drier as you
move west.
• May to October is HOT. It cools in November, and this is when most
germination occurs.
                  Historical Vegetation Patterns

Mixed woodland - containing oaks (Quercus buckleyi) and juniper
(Juniperus ashei)

Savannas - grasses with clusters of trees and shrubs, such as live oak
(Quercus fusiformis).

Along rocky cliffs - pure stands of juniper (Juniperus ashei)

Along rivers - cypress, pecan, hackberry and sycamores
      Modern Vegetation Patterns

        Grazing by domestic stock

       White-tailed deer population

           Suppression of fire

Result: Invasion by juniper and other woody
      species into open grassy areas
